Adjust Hue

Quick Reference to Scripting Command
a=HUE(p)
Items in CAPS are 0/1 switches or switches with more options than 0/1.


Operation Example

This operation provides you with one slider for adjusting the amount or degree of hue change for the specified area. Hue adjustment is applied primarily to images which have been scanned too red or too green. By adjusting the hue up or down, you can add either more green (up) or red (down) to the image.

In general you will only need to make small changes to the hue setting to get the desired correction. Altering the Hue setting by a great amount will produce a great amount of change.

Hue Controls

Trends

Some of the controls have a Trend button next to them. These trend buttons allow you to set variables over a series of frames. Each frame of any animation may be thought of as a slice of time. The trends allow you to alter some, all, or none of the variables for a particular time slice. Trend graphs have equidistantly spaced vertical lines. For animations under 100 frames in length, each of these lines represents a frame in the animation. The number of frames in any one sequence can be altered using the Sequence controls item from the Timeline pull down menu. Animation lengths of 100 - 999 frames will be represented with a vertical bar being 10 frames, and animation length greater than 1000 frames will have a vertical bar for every 100 frames. Click here to view more information on Trends.

Hue

This control ranges from -180 to 180 and controls how much each pixels hue value will be shifted. Positive hue increases will result in more green being applied to the image, and negative hue values will add more red to the image. In general this is designed to be a correction tool only. However, you can produce some interesting color effects by pushing the hue value too far.
